They don't honor deals or promotions that they advertise.
The husband and I went in to the dealership yesterday to look at the 2017 Volts since they were offering 0% financing. We have excellent credit and definitely qualify. They wouldn't honor it since they took money off the MSRP of the vehicle.
Apparently you can only have one or the other- a decreased MSRP or good financing. We took our business elsewhere.
Don't waste your time with these people. They want to get you in and then scam you. Honor your promotions and stop using BS sales tactics.
